Catalog Service not available in WEBIDE after adding OVP Plugin

[marcus_schiffer]

Hi experts,

we had a working Cloud Connector destination from a S/4 HANA System from SAP CAL to the HANA trial cloud. Using WebIDE worked as expected. After adding the OVP plugin we get errors while connecting to the Service Repository from WEBIDE.

Not sure whether ist comes from OVP plugin but the message is: "Catalog Service Unavailable. Please try again".

In the logs we find errors of type

'/IWFND/OM_MED_CATAL_ODC_0001_UC' '01' 'DEFAULT'

We cannot however find the service in the repository of the SAP S/4 system.

What would be the solution ?

Hi There

Most likely, there is a Version 2 of the catalog service in your sap system.  Check this in /IWFND/MAINT_SERVICE

The call from the Web IDE goes to Version 1 of the Catalog Servic(/IWFND/CATALOGSERVICE/ServiceCollection?$format=json).

The url to call version 2 would be /IWFND/CATALOGSERVICE; version=2?$format=json).

Since you cannot force the WebIDE to change the URL it calls, you can disable Version 1 of the service in SAP, so that even a call without the version=2 addition executes the version 2 of the service.

I "disabled" version 1 in sap by removing the "System Alias" setting in /IWFND/MAINT_SERVICE. Then click Button "load Metadata" (just to be sure).

Now the call from the Web IDE is supposed to work.

Hope it helps.

Found this solution after examining the logs and disabling the version 1 it solved the issue.
